DEWEY H. BITNEY, ALBION, MICHIGAN, ASSIGNOR TO UNION STEEL PRODUCTSCOMPANY, or ALBION, MICHIGAN ANCHOR INSERT FOR CONCRETE TVORKApplication filed February 11, 1927. Serial No. 167,418.

The main object of this invention is to provide a concrete hanger insertfor the supportv of ceilings and the like which is securely embeddedwithin the concrete, may be easily adjusted or applied to the form, andone in which the lathing or supported element may be secured in a veryeffective manner and at such points as are best adapted to the elementsupported.

Objects pertaining to details and economies of my invention willdefinitely appear from the detailed description to follow. The inventionis clearly defined and pointed out in theclaims.

A device embodying the features of my improvements is clearlyillustrated in the ace companying drawing forming a part of thisapplication, in which: 7

Fig. 1 is afragmentary sect1on through a concrete ceiling beam and formshowing the relation of my improved concrete hanger insert in use.

Fig. 2 is, a fragmentary section with the form removed and with one ofmy improved hangers engaged with the insert.

Fig. 3 is a detail section corresponding to that of Fig. 2 with afragment of expanded metal lath secured in position.

Fig. 4 is a fragmentary perspective of one of the inserts. r

Fig. 5 is a perspective view of one of the hangers.

Referring to the drawing, 1 represents a beam form and 2 the concretebeam or structure. My improved hanger comprises a channel insert 3formed of sheet metal which is the desired length of the structure orformed in suitable lengths, as may be most desirable.

The insert 3 has downwardly converging side walls 4 one of whichterminates in an inwardly and upwardly turned flange 5. This flange isspaced from the opposlte wall providing a space 6 for the passage of thehooks 7 of the hanger 8. The hanger is preferably a loop of wire, thehooks being disposed in the same direction so that they may both beengaged over the supportlng flange 5. r

9 represents the expanded metal lathing,

this being shown conventionally, and the hangers are passed about thepart 10 of the lathing prior to engagement over the supporting flange 5.The end of the loop is then twisted as indicated at 11 until the lath issecurely clamped against the beam, ceiling or other surface in which theinsert is set.

By converging the walls of the insert downwardly the concrete has a verysecure hold thereon. The insert is preferably provided with a series ofholes 12 through the top or web thereof to receive the nails 13 by whichthe insert is temporarily secured to the form so that it is notdisplaced as the con- 3-65 crete is poured.

WVhen the form is removed it is pulled off these nails and the nails maybe bent up into the channel if desirable.

My improved concrete hanger insert is sim- 370 ple and economical instructure, is capable of use in numerous relations, and the supportedelement may be very quickly and easily secured thereto.

Having thus described myinvention what I claim as new and desire tosecure by Letters Patent is:

1. An anchor for concrete work comprising a channel member havingforwardly converging side walls, one of said side walls having aninwardly and rearwardly turned flange at its edge, there being a spacebetween said flange and the opposite side wall, which is without aflange, loop-like tie members provided with hooks engageable with saidflange 3 55 through said space, said tie members being of bendablematerial whereby they may be twisted to clamp a supported element.

2. An vanchor for concrete work comprising a channel member havingforwardly go converging side walls, one of said side walls having aninwardly and rearwardly turned flange at its edge, there being a spacebetween said flange and the opposite side wall which is without aflange, and tie membersprovided with hooks engageable with said flangethrough said space.

3. An anchor for concrete work comprisring a channel member adapted tobe embedded 1n a concrete body facing outwardly one of the side Wallshaving a continuous inwardly and rearwardly turned. flange, the 7 otherbeing Without a flange, and tie members provided with hooks engageablewith said flange.

In witness whereof I have hereunto set my hand. I
